Good Day.
How do I get Layer 3 etherchannel to communicate with my Management VLAN ? My etherchannel is Up Up, but my VLAN stays DOWN DOWN.
Any help will be much appreciated......
Here is a sample of my configs

interface Port-channel50

Hi,
add least one physical port on the vlan

An SVI will only come up if an active Layer 2 ports either exists in than Vlan (i.e an access port) or a Trunk port which carries that Vlan tag.
Your connections to other switches are Layer 3 (i.e they have an IP address) so as far as the switch is concerned, the SVI is not needed as there is no active ports requiring it.
A vlan is a layer 2 entity so it will not be tagged across your Layer 3 link, hence why the SVI believes its not yet needed so stays down.
If you just need an IP address for management of the device then use a Loopback interface as they are virtual also but do not require an active Layer 2 link to come up.
Thanks
